Just an idea. I like the .40 S&W round. I like the L-Frame. I've been looking at the .40 S&W and the L-Frame and wondering. I understand that folks have set the L-Frame up in .44 Special. I was wondering if I could set up a L-Frame in .40 S&W. The idea I have is to use a 686. Have the cylinder and chamber line bored, then throated, etc. for 180 gr. bullets. Have the back of the cylinder faced off to allow the use of moon clips. If it could be cut for 10mm, so much the better as I could then fire either round. Is this a workable idea? If so, who would be a good gunsmith to contact for the work. If there is a particular -# of the 686 to use, please state so and why. Sincerely. Bruce.
